Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669908, here are decompositions:

11 + 8669897 = 8669908
29 + 8669879 = 8669908
47 + 8669861 = 8669908
131 + 8669777 = 8669908
239 + 8669669 = 8669908
251 + 8669657 = 8669908
257 + 8669651 = 8669908
281 + 8669627 = 8669908

Showing the first eight; more decompositions exist.
